Customer Reviews (5.0 / 5 · 5 reviews)

Joshua ★★★★★

The hex profile fits my socket perfectly without slipping, and the fully threaded shaft let me secure a tight bracket assembly. These are solid little bolts for the price.

Hazel ★★★★★

The cadmium coating on these bolts gives them a nice, even finish that resists corrosion right out of the pack. They threaded smoothly into the steel brackets I’m mounting, and the fully threaded shank gave me plenty of grip for a tight fit. Exactly what I needed for this job.

Ava ★★★★★

Finally found bolts with threads running the full shank length, which made a huge difference for a tight metal bracket assembly where every millimeter of grip mattered. The cadmium coating gives them a nice consistent finish too.
